In case it does, immediately flush affected
area with water, and seek medical help if
necessary.!Electrolyte drops coming into contact
with the vehicle paint finish can be
completely removed only while in the
liquid state and by applying plenty of
water.

ger-side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your
interior rear view mirror or glance over your
shoulder before changing lanes.
